**Proof Right triangles inscribed in circles (video) Khan**

Right triangles provide the basis for many mathematical things, such as finding the distance up a slope if you only know the height of the hill and determining how wide the hill is.... Right Triangles. Right triangles are triangles in which one of the interior angles is 90 degrees, a right angle. Since the three interior angles of a triangle add up to 180 degrees, in a right triangle, since one angle is always 90 degrees, the other two must always add up to 90 degrees (they are complementary).

**C Program to Calculate Area of a Right Angled Triangle**

Right triangles provide the basis for many mathematical things, such as finding the distance up a slope if you only know the height of the hill and determining how wide the hill is.... Right-angled triangle is a triangle in which one angle is a right angle (90 degree). The sum of the other two angles of right-angled triangle is 90 degree. The relation between sides and angles of right angled triangle is the foundation of trigonometry and pythagoras theorem.

## How To Know If Its A Right Angled Triangle

In the figure given above, ∆ABC is a right angled triangle which is right angled at B. The side opposite to the right angle, that is the longest side, is called the hypotenuse of the triangle…

- By measuring it's one of its angle opposite to the longest side of the triangle . If that angle is 90° then the triangle is right angled triangle. If that angle is 90° then the triangle is right angled triangle.
- Let’s take an example Can 3, 4, 5 be the side of a right angled triangle? We know that, Hypotenuse is the longest side. So, Hypotenuse = 5
- In this right-angled triangle with sides a, b, h, we have drawn in a line from the right-angle perpendicular to the hypotenuse, of length H. If the triangle's base is the hypotenuse then this is its height so that the area of the triangle is hH/2 .
- We know that a right triangle is a triangle having a right angle, where the side opposite the right angle is the hypotenuse, and the perpendicular sides are the legs of the ri … ght triangle.
